Full-text available
For most major movies, consumers have a choice to watch them in a theater or on home video. While each viewing channel has its own advantages and disadvantages, consumers are watching the same underlying product—a specific movie. An unanswered question is whether consumers enjoy watching a specific movie more in a theater or video setting. Using IM...

Significance Why are some narratives (e.g., movies) or other texts (e.g., academic papers) more successful than others? Narratives are often described as moving quickly, covering lots of ground, or going in circles, but little work has quantified such movements or tested whether they might explain success. We use natural language processing and mac...
Article
Before their launch, many new products generate word of mouth (WOM) on social media. Such WOM typically increases toward the release date and contains sudden spikes. These spikes capture manifestations of peak consumer attention and are therefore of managerial importance, yet they have not received research attention. This article is the first to p...

In the early stage of film development when producers assemble a development team, it is important to understand the means by which different team members may contribute to the film's box office. Building upon theories from marketing and sociology, we propose that these contributions arise from team members' positions, or embeddedness, in a social...

Article
Full-text available
We develop a methodology to predict box office performance of a movie at the point of green-lighting, when only its script and estimated production budget are available. We extract three levels of textual features (genre and content, semantics, and bag-of-words) from scripts using screenwriting domain knowledge, human input, and natural language pr...

The pharmaceutical industry leads all industries in terms of R&D spend. Portfolio management in new drug development is extremely challenging due to long drug development cycles and high probabilities of failure. In 2010, a pharmaceutical company like GlaxoSmithKline (GSK) spent over USD 6 billion in R&D expenditure and managed a total of 147 R&D p...
Chapter
This chapter explores the academic literature and empirical evidence associated with the strategic and tactical opportunities available to pharmaceutical firms confronted with the loss of patent protection on their branded drug. The marketing dimensions of product innovation, pricing, and brand equity options are considered together with exclusivit...
Article
We empirically examine the financial impact of production duration in a multi-stage production process for creative products. In particular, we analyze a novel data set from the movie industry to shed light on how the total production time and duration of individual stages affects box office revenues. We find that total production time is negativel...
Article
Full-text available
Strategic preannouncement of a new product launch by a firm creates a pent-up demand (or consumers committed to purchase prior to launch) for the new product. The level of the pent-up demand depends, among other factors, on the timing and the reputation of the firm announcing the new product; it is critical in shaping up the diffusion process of th...
Article
Full-text available
In a viral marketing campaign organizations stimulate customers to forward marketing messages to their contacts. To optimize a viral campaign it is necessary to predict how many customers will be reached, how this reach evolves, and how it depends on pro- motion activities. A new Viral Branching Model can provide these results. It is based on insig...
Article
This article analyzes one key characteristic shared by a growing number of industries. Specifically, their products and services are continuously monitored and evaluated by local third-party ratings systems. In this study, we focus on understanding the local drivers of restrictive age-based ratings in the motion picture industry and the effect of l...
Chapter
Full-text available
The modeling framework developed here to address the positioning and pricing of a product line assumes that products differ in price and in a single physical attribute. It incorporates a flexible representation of customer heterogeneity, allowing for price-sensitive demand, and a rich class of supply-chain cost models. A key characteristic of poten...
Article
A central focus of database marketing is on predicting customer defection (churn). We argue this focus would be better placed on predicting when customers become inactive, which often precedes the time at which the customer terminates the contract, and represents a behavioral regularity found across several contractual markets. We model customers'...

Full-text available
In a viral marketing campaign, an organization develops a marketing message and encourages customers to forward this message to their contacts. Despite its increasing popularity, there are no models yet that help marketers to predict how many customers a viral marketing campaign will reach and how marketers can influence this process through market...
Article
This paper reports the development and implementation of a decision support system in a non-traditional domain — the motion picture industry. The approach reported here is evolutionary, and the model was designed to assist exhibition executives in movie scheduling. After an earlier successful collaboration in scheduling a single theater with multip...

Article
In this paper, we focus on the perspective and business model of the rentailer — a retail outlet that rents and sells new and used home video titles. This requires predicting the consumer's decision to rent or buy a particular title, segmenting its customer base, and pricing new and used titles. We develop a new model based on a simple heuristic fo...

hen a DVD title is announced prior to actual distribution, consumers can often preorder the title and receive it as soon as it is released. Alternatively, once a title becomes available (i.e., formally released), consumers can obtain it upon purchase with minimal delay. We propose an individual-level behavioral model that captures the aggregate pre...

Full-text available
Globalisation, liberalization and rapid technological developments have been changing business environments drastically in the recent decades. These trends are increasingly exposing businesses to market competition and thus intensifying competition. In such an environment, the role of marketing management support systems (MMSS) becomes exceedingly...
Article
Full-text available
New products are often launched sequentially, by different firms, and the purchasing decisions are sometimes made by dyads. This paper proposes a new model that explicitly considers dyadic decision making in drug prescription and allows assessment of the relative influence that physicians and patients have in making decisions concerning new as well...
Article
A stochastic (diffusion) sales response model to advertising is postulated. Optimum advertising policies are then found by solving a stochastic control problem with reflecting boundaries. Analytical results are obtained and interpreted to yield insights regarding a firm's risk behaviour and its optimal advertising policy.

Movie studios often have to choose among thousands of scripts to decide which ones to turn into movies. Despite the huge amount of money at stake, this process--known as green-lighting in the movie industry--is largely a guesswork based on experts' experience and intuitions. In this paper, we propose a new approach to help studios evaluate scripts...

This paper describes a model that generates weekly movie schedules in a multiplex movie theater. A movie schedule specifies within each day of the week, on which screen(s) different movies will be played, and at which time(s). The model consists of two parts: (i) conditional forecasts of the number of visitors per show for any possible starting tim...

Article
Full-text available
The motion picture industry has provided a fruitful research domain for scholars in marketing and other disciplines. The industry has high economic importance and is appealing to researchers because it offers both rich data that cover the entire product lifecycle for many new products and because it provides many unsolved “puzzles.” Although the am...

E-commerce has proved to be fertile ground for new business models, which may be patented (for up to 20 years) and have potentially far-reaching impact on the e-commerce landscape. One such electronic market is the reverse-auction model popularized by Priceline.com. There is still uncertainty surrounding the survival of such new electronic markets...

We develop an econometric model to study a setting in which a new product is launched first in its domestic market and only at a later stage in foreign markets, and where the product's performance (“demand”) and availability (“supply”) are highly interdependent over time within and across markets. Integrating literature on international diffusion,...

In many new product development (NPD) situations, the development process is characterized by uncertainty, and no single development approach will necessarily lead to a successful product. To increase the likelihood of having at least one successful product, multiple approaches may be simultaneously funded at the various NPD stages. The managerial...

Full-text available
For most firms, new product development is the engine for growth and profitability. A firm's new product success depends on its ability to manage the product development process in a way that employs scarce resources to achieve the goal of the firm as well as the specific project's objectives. Simple and measurable performance metrics have been pro...

This paper shows how two different theoretical approaches to model innovation adoption, network threshold modeling and random utility modeling, both result in discrete-time hazard models, a popular statistical modeling approach to study innovation adoption and diffusion. The paper emphasizes the need for careful situational analysis prior to model...
Article
Full-text available
We show how one can specify micro-level hazard models of adoption that separately represent the awareness and evaluation/choice stage of the adoption decision process even when one observes only the final outcome, i.e. adoption or not. These models can be derived from random utility theory. Using a small simulation study, we show that the two-stage...

In spite of the high financial stakes involved in marketing new motion pictures, marketing science models have not been applied to the prerelease market evaluation of motion pictures. The motion picture industry poses some unique challenges. For example, the consumer adoption process for movies is very sensitive to word-of-mouth interactions, which...
Article
Full-text available
Managing the allocation of shelf space for new products is a problem of significant importance for retailers. The problem is particularly complex for exhibitors—the retailers in the motion picture supply chain—because they face dynamic challenges, given the short life cycles of movies, the changing level of demand over time, the scarcity of shelf s...

Many products carry a warranty that offers protection for the consumer against low quality. These warranties are often two dimensional, such as an automobile warranty that guarantees repair up to a certain time and mileage after sale. This paper considers the problem of assessing the size of a reserve needed by the manufacturer to meet future claim...

The development of new products inevitably leads to tradeoffs among product performance, time to market, and development costs. In addition, the unit cost of the product, which is determined by the product performance, is also affected by the design process. In this paper, we present a model framework that examines the interaction of these factors....

We model joint production-marketing strategies for two firms with asymmetric production cost structures in competition. The first firm, called the “Production-smoother,” faces a convex production cost and a linear inventory holding cost. The second firm, called the “Order-taker,” faces a linear production cost and holds no inventory. Each firm is a...
